EXTENSIBLE BED-BOTTOM FOR IRON BEDSTEADS.

To all whom it may concern.-

Be it known that I, FRANCIS M. TINKHAM, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in EX- tensible Bed-Bottoms for Iron Bedsteads, of

g which the following is a specification.

This invention relates to bedsteads, and particularly to bed-bottoms for iron bedsteads, andhas for its object the production of a bed-bottom longitudinally and transversely adjustable; and it consists in the parthree sections, the central section comprising the longitudinal supports 2 2 2, having the transverse supports a, and the right and left hand sections comprising, respectively, the longitudinal supports 4 4, the transverse supports b, and the longitudinal supports 3'3, and the transverse supports 17 b. The longitudinal supports 2, 3, and4 of these sections consist of fiat metal strips used edgewise and united together by the transverse supports used flatwise, and which are of substantially the same dimensions as the longitudinal sup ports, the ends of the latter being turned downward and riveted to the said supports 2, 3, and 4. The central section is made of these longitudinal supports equally spaced, and

' each of the side sections is made of two 1ongitudinal supports of a width about equal to half the width of the central section. The ends of the longitudinal supports of the central section on one end thereof and the. end

' of the outer longitudinal support of the side section on one end thereof are given a quartor-turn twist, .as at w, and these ends are then turned up and over to form the hooks 2 for engaging with the end rail of the bedstead. The opposite ends of said supports 2,

which the ends of the said supports are passed,

and a pin 7" or other convenient method for preventing them from slipping off from said supports is employed.

In constructing this bed-bottom the central section is first made. then completed, with the exception that the inner oneof the two longitudinal supports 3 3 and 4 4 is left unattached to its several transverse supports. The inner one of the two supports 3 and 4 of each of the side sections is then'passed under the transverse supports of the central section, as shown in Fig. 1 of the drawings-and the transverse supports of the side sections are then riveted to each of the inner longitudinal sections which are located under the transverse supports a a of the central section, thereby attaching the side and central sections together, but permitting the side sections to be moved trans The side sections are versely on said central section to adjust the transverse supports on each end of the sidesections are placed outside of and close up to the transverse support a on each end of the 1 central section. -To securely hold the side sections level with central section, the clips 6 6 are riveted to the side sections near their inner corners, as shown. These clips, securely fastened to the support b, project inward and over the supports a a, close to the longitudinal support which lies under said supports ct a. The transverse supports on each end of the central section are thus engaged on their upper and under sides by the end sect-ions, and supported by such engagement and by the bearing of the supports 79 and b on the upper edge of the outside longitudinal supports of the central section, yet having a free sliding movement thereon transversely thereof. Fig. 2 shows in dotted lines the extreme position to which the side sections may be moved toward each other on the central section.

A bed-bottom constructed according to my invention as herein described is one easily adapted to any of the ordinary iron bedsteads and is adapted to be closely fitted to the side rails of said beds and affords perfect support for either a woven-wire mattress or any of the coiled-spring constructions in common use. It is of small cost and of very light weight and can be closely folded for shipment.

Having thus described my invention, what I claim, and desire to secure by LettersPatent, is

1. In a bed-bottom, a central stationary section consisting of the parallel longitudinal supports 2which are united by the transverse supports a, which extend in opposite directions from the central longitudinal supports 2, combined with longitudinal supports 3, 4;, which are united in pairs by the transverse supports 1), b, which extend across the tops of the outer longitudinal supports 2, and the supports 6 which catch upon the tops of the transverse supports a; the longitudinal supports being provided with hooks upon their ends, and the transverse supports 3, 4:, being horizontally adjustable in relation to the supports 2, whereby the width of the bed-bottom can be increased or decreased at will, substantially as shown.

2. In a bed-bottom, a stationary longitudinal support 2, provided with hooks 2 at one end, the transverse supports a which connect the supports 2 rigidly together, and the removable hooks 2", which are applied to the outer ends of the longitudinal supports, combined with the removable longitudinal supports 3, 4, the transverse supports 12, b, which unite them in pairs, and which supports catch over the top edges of the two outer stationary longitudinal supports 2; the supports 6 secured to the inner ends of the transverse supports I), b, and which supports catch over the tops of the stationary transverse supports a, and the pins 7 a which prevent the removable hooks from becoming detached, all combined and arranged to operate, substantially as specified.

3. A bed-bottom for iron bedsteads consisting ofacentral section, separate side sections transversely movable on said central section, means of engagement between said side and central sections for holding them in the same plane, and fixed and longitudinally-adjustable end supports on the opposite ends of said sections, substantially as described.
